超聲波金屬焊接機(jī)是通過高頻的機(jī)械振動(dòng)對(duì)非鐵磁性的金屬物料工件進(jìn)行焊接。在焊接過程中，將其中一個(gè)工件固定，另一個(gè)工件以20kHz的頻率在其表面進(jìn)行循環(huán)往復(fù)的振動(dòng)，同時(shí)對(duì)工件施加壓力，使工件間形成一種牢固的結(jié)合，從而達(dá)到焊接的效果。整個(gè)焊接過程可以被精確地控制，同時(shí)不會(huì)在金屬表面產(chǎn)生多余的熱量，焊接牢度強(qiáng)。在焊接金屬制品時(shí)，既不要添加任何粘接劑、填料或溶劑，也不消耗大量熱源，具有操作簡便、焊接速度快、焊接強(qiáng)度高、生產(chǎn)效率高等優(yōu)點(diǎn)。因此，超聲波焊接技術(shù)越來越廣泛地獲得應(yīng)用。

    Ultrasonic metal welding is a mechanical process, which translates electric power in high frequency into mechanical vibration via transducer and acts on the articles to be processed, Their surface in contact produces high-frequency friction which makes heat, gets cohered and welded, During the welding, there is neither current passing through the parts welded,nor welding arc in the mode of electric weld. As ultrasonic welding nerver brings about heat exchange or resistivity, it is an ideal welding system for non-ferrous metal, It is particualarly suitable to be used to treat thin and small material on a single-spot, multi-spot, square-shaped, bar-shaped, single-layer, multi-layer or compound basis, such as aluminum, nickel, copper, silver, etc.
